Do we need to change passwords on this and other affected sites (metabans) ?

This is regarding a recent vulnerability exposed in Cloudflare's infrastructure. For months now, there has been a vulernerability that allowed data transmitted between Cloudflare's proxy servers and the target server to be exposed.

Just reading up on this clusterfuck... and I would say: better safe than sorry and change passwords

Although chances are very small your personal info was cached:

An additional problem was that Google (and other search engines) had cached some of the leaked memory through their normal crawling and caching processes. We wanted to ensure that this memory was scrubbed from search engine caches before the public disclosure of the problem so that third-parties would not be able to go hunting for sensitive information.

Our natural inclination was to get news of the bug out as quickly as possible, but we felt we had a duty of care to ensure that search engine caches were scrubbed before a public announcement.

The infosec team worked to identify URIs in search engine caches that had leaked memory and get them purged. With the help of Google, Yahoo, Bing and others, we found 770 unique URIs that had been cached and which contained leaked memory. Those 770 unique URIs covered 161 unique domains. The leaked memory has been purged with the help of the search engines.
